We had just parked at the Shell Island overlook on the Oregon coast and I was wondering what to sketch, when I spotted a sealion surfing in on a big wave. The sealion was just underwater and obviously using the momentum of the wave. I never seen that before ... but seldom am I there when the waves are so big. Look carefully and you'll see his underwater blob in the first sketch.
The second sketch is looking south from the same overlook.
